ATTACHMENT FOB PAPER MACHINES.

Application filed August 8, 1928. Serial No. 656,319.

In packin and marketing fruits of various kinds, ithas been customary to wrap each article in paper for the purpose of excluding I air, dust and dirt, and preventing the fruits from becoming bruised or marred by rub bing contact in the package. Tn shipping such fruit-s by water, particularly a long distance on the ocean, it has been found desirable to impregnate the wrapping paper with a substance, such as oil or wax which will be impervious to moisture. The wrapping paper after passing through the paper machine, has been treated in a separate oil or waxing machine, the process involving a separate-and distinct operation from thatofpass ing through the paper machine. This additionaloperation has added considerably to the'labor and expense of treating the wrap ping paper and furthermore the oil or waxmg machine has added considerably to the cost and upkee of the plant.

The object o my invention is to save steps and time in the process and eliminate entirely the additional oil dipping machine.

A further object is to greatly simplify and reduce the first cost of treating the paper.

The invention consists generally in various constructions and combinations all as hereinafter described and particularly pointed out in the claims.

In the accompanving drawings forming part of this specification,

Figure 1 is a sectional view of a portion of a paper machine illustrating the application of my invention thereto;

Figure 2 is a plan sectional view on the line 2-2 of Figure 1. a

Tn the drawings, 2 represents the frame of the machine of'any suitable or preferred construction; 3 is one of the, paper rolls over which the webof ,pa er 4 passes. A roll 5 is mounted'in the mid le ortion of the frame above'which are rolls 6, 8 and 9, to which the web of paperis delivered in the usual way -in machines of this type. As the web passes'between the rolls 5 and 6, it is wound on a roll 10; mounted in a reel 11. This reel is also adapted for supporting a roll 10, the

reel being reversed when one roll is filled to permit the removal of the pa er from the filled roll while the paper is ing wound on the other roll. All this is well-known construction in a paper machine to which ll make no claim of novelty.

llnstead of having a separate machine for impregnating the paper with oil or .wan, T

,15 are pivoted at 16 and havearms 17 to which tension springs 18 are connected;'said brackets being pivoted on the Wall of the container 12 and having sockets wherein threaded rods 19 are adjustable by means of nuts 20.

The tension of the springs 18 is suflicient to t hold the roll 14 in contact with the roll 5 for the deposit of the oil on the peripheral surface of the roll 5 but whenever desiredthe nuts 20 may be loosened and the rods 19 withdrawn to pull-the oil distributing roll out of the body of oil and out of contact with the roll 5,- thus allowing the roll 5 to revolve in the container without having any oil deposited on its peripheral surface.

Upon the opposite side of the roll 5 is a blade 21 having end pivots 22 in the walls of the container'and provided with a thin edge 23 that is adapted to bear on the surface of the roll 5 and spread the film of oil thereon. Springs 24: are connected with the blade 21 and operate to hold the edge 23 in contact with the surface of the roll with a a0 yielding pressure. This pressure may be varied so thatthe coating or film of oil on' the roll Ina be spread out very thin so that only a smal quantity is allowed to contact with the paper web or the blade may be adjusted so that it will bear lightly on the roll 5 and allow a considerable accumulation of oil thereon and thus the operator of the machine can easily regulate the quantity de-' livered to the paper web, and the degree that the web is impregnated with the oil or wax.

For the urpose of regulating the pressure of the bla e on the roll, I prefer to provide an arm 25 thereon supporting a welght 26 which ismovable back and forth on the arm 10a for the purpose of increasing or decreasing the pressure of the blade on the roll and the depth of the film or peripheral coating of oil thereon. lit will be noted that this attachment can be easily and quickly applied to a T 1 standard paper machine without any re-adjustments or alterations in the an chine; that a the expense of construction of the attachment is comparatively small, involving only the container and the distributin roll and scraper blade, thus eliminating tie expense ofa separate dipping machine and saving the space which would be required in a paper mill for such a machine.

ll claim as my invention: I

1. In a paper machine, a receptacle adapted to contain a supply of paper impregnating material in liquid form, a distributing roll partially immersed in the liquid in said container, a series of paper machine rolls arranged one above the other, the lower roll of the series being positioned to contact with said distributing roll to receive therefrom a coating of the liquid in said container, the web of paper passing around the upper rolls of the series'and contacting with the lower roll of the series to be impregnated with the coating thereon for the purpose specified,

and means bearing. on the peripheral surface of said lower roll of the series for evenly spreading the coating in a film of suitable thickness thereon.

2. In a paper machine, a container for liquid paper impregnating material, feed rolls above the liquid level in the container, and means separately adjustable respectively for applying the liquid to the entire surface of one unimmersed feed roll, and for spreading the material in a thin filament entirely across said roll, to be carried to the paper for adsorption thereby.

3. A process for impregnating paper with oil which consists in drying the paper, and

then afterwards and while dry applying the oil to the paper.

4. A rocess for impregnating paper with oil whic consists in drying the paper by heat and then afterwards and while dry applying the oil'to the paper.

5. In combination with a dryin device of a paper machine, an oil receptac e adjacentdepth ofthe'liquid oil film upon the roll be- I:tgore the paper comes in contact with said 7. In combination with the drying roll of a paper machine of an oil receptacle, a roll arran ed to receive oil from the receptacle, and a so arranged so that the paper is held against it after leaving the heating roll, and means for regulating the depth of the liquid oil film upon the roll before the paper comes in contact with said film, said means comprising a Wiper element yieldably engaging the roll throughout its len th. V

In witness whereof, I ave hereunto set my hand this 28th day of July, 1923.
